Rational design of induced regeneration via somatic embryogenesis in the absence of exogenous phytohormones Open
Plants have a remarkable regenerative capacity, but this varies widely among species and tissue types. Important crop cultivars show regenerative recalcitrance, which is a major obstacle for the application of modern plant propagation and …
<span>PLETHORAs</span> shape Arabidopsis phyllotaxis through modulation of patterning robustness and accelerated inflorescence development Open
Summary Phyllotaxis is the arrangement of lateral organs on a stem axis, which in Arabidopsis follows a spiral pattern. We previously described that loss of three PLETHORA (PLT) transcription factors shifts the phyllotactic spiral to novel…
The <i>Medicago truncatula</i> lncRNA <i>ENOD40</i> is a mediator of <i>microRNA169</i> -controlled <i>NF-YA</i> activity in nodule initiation Open
The hallmark of the legume lncRNA EARLY NODULIN40 ( ENOD40 ), involved in rhizobium-induced nodulation, is the presence of a highly conserved stretch of 24 nucleotides, designated box2, preceded by a small open-reading-frame (sORF) coding …
Shaping root architecture: towards understanding the mechanisms involved in lateral root development Open
Plants have an amazing ability to adapt to their environment, and this extends beyond biochemical responses and includes developmental changes that help them better exploit resources and survive. The plasticity observed in individual plant…
PLETHORA transcription factors promote early embryo development through induction of meristematic potential Open
Plants are dependent on divisions of stem cells to establish cell lineages required for growth. During embryogenesis, early division products are considered to be stem cells, whereas during post-embryonic development, stem cells are presen…
Steep logarithmic increase of genetic variation in natural <i>Arabidopsis thaliana</i> accessions across geographic scales Open
Arabidopsis thaliana’s large native range across Eurasia and display of considerable genetic variation is key to its increasing use in eco-evolutionary studies. The structure and amount of this genetic variation has been studied on various…
Arabidopsis ribosomal RNA processing <i>meerling</i> mutants exhibit suspensor-derived polyembryony due to direct reprogramming of the suspensor Open
Embryo development in Arabidopsis (Arabidopsis thaliana) starts off with an asymmetric division of the zygote to generate the precursors of the embryo proper and the supporting extraembryonic suspensor. The suspensor degenerates as the dev…
The dual role of the <span>RETINOBLASTOMA‐RELATED</span> protein in the <span>DNA</span> damage response is coordinated by the interaction with <span>LXCXE</span>‐containing proteins Open
SUMMARY Living organisms possess mechanisms to safeguard genome integrity. To avoid spreading mutations, DNA lesions are detected and cell division is temporarily arrested to allow repair mechanisms. Afterward, cells either resume division…
SCHIZORIZA domain–function analysis identifies requirements for its specific role in cell fate segregation Open
Plant development continues postembryonically with a lifelong ability to form new tissues and organs. Asymmetric cell division, coupled with fate segregation, is essential to create cellular diversity during tissue and organ formation. Ara…
Redundant <i>PLETHORA</i> activity promotes development of early embryonic cell lineages in Arabidopsis Open
The BABY BOOM/PLETHORA4 (BBM/PLT4) transcription factor has received much attention due to its ability to induce somatic and zygotic embryogenesis, two processes of pivotal importance in plant breeding. Loss of additional AINTEGUMENTA-LIKE…
RETINOBLASTOMA RELATED (RBR) interaction with key factors of the RNA-directed DNA methylation (RdDM) pathway Open
Summary Transposable elements and other repetitive elements are silenced by the RNA-directed DNA methylation pathway (RdDM). In RdDM, POLIV-derived transcripts are converted into double stranded RNA (dsRNA) by the activity of RDR2 and subs…

Cell-by-cell dissection of phloem development links a maturation gradient to cell specialization Open
Root meristem controls The plant meristem, a small cluster of stem cells generates all of the cell types necessary for the plant’s indeterminate growth pattern. Roszak et al . use single-cell analyses to follow development from the stem ce…
The dual role of the RETINOBLASTOMA-RELATED protein in the DNA damage response is spatio-temporally coordinated by the interaction with LXCXE-containing proteins Open
Living organisms face threats to genome integrity caused by environmental challenges or metabolic errors in proliferating cells. To avoid the spread of mutations, cell division is temporarily arrested while repair mechanisms deal with DNA …
A phosphorylation code regulates the multi-functional protein RETINOBLASTOMA-RELATED1 in <i>Arabidopsis thaliana</i> Open
The RETINOBLASTOMA-RELATED (RBR) proteins play a central role coordinating cell division, cell differentiation and cell survival within an environmental and developmental context. These roles reflect RBR ability to engage in multiple prote…
Arabidopsis CULLIN3 Genes Regulate Primary Root Growth and Patterning by Ethylene-Dependent and -Independent Mechanisms Open
CULLIN3 (CUL3) together with BTB-domain proteins form a class of Cullin-RING ubiquitin ligases (called CRL3s) that control the rapid and selective degradation of important regulatory proteins in all eukaryotes. Here, we report that in the …
ErbB-3 BINDING PROTEIN 1 Regulates Translation and Counteracts RETINOBLASTOMA RELATED to Maintain the Root Meristem Open
The ErbB-3 BINDING PROTEIN 1 (EBP1) drives growth, but the mechanism of how it acts in plants is little understood. Here, we show that EBP1 expression and protein abundance in Arabidopsis (Arabidopsis thaliana) are predominantly confined t…
Geometric cues forecast the switch from two‐ to three‐dimensional growth in <i>Physcomitrella patens</i> Open
Summary During land colonization, plants acquired a range of body plan adaptations, of which the innovation of three‐dimensional (3D) tissues increased organismal complexity and reproductivity. In the moss, Physcomitrella patens , a 3D lea…
EBP1 Regulates the Capacity of Protein Translation Open
Arabidopsis pgEBP1-YFP line expressing EBP1-YFP under the EBP1 promoter were grown in 3 repeats alongside with the same number of repeats of the control 35CaMVS:GFP (ref) for 7 days at 16/8 light and 150-200 seedlings were frozen in liquid…

A Plausible Microtubule-Based Mechanism for Cell Division Orientation in Plant Embryogenesis Open
Oriented cell divisions are significant in plant morphogenesis because plant cells are embedded in cell walls and cannot relocate. Cell divisions follow various regular orientations, but the underlying mechanisms have not been clarified. W…
